13 November 2008The research of multi-parameter sensor based on two-mode highly birefringent photonic crystal fibers
Two-mode highly birefringent optical fibers support two spatial modes. The two spatial modes can be used to set up two
detectors. The birefringence would change with the variety of environment. Therefore, two-mode highly birefringent
optical fibers can sense two parameters synchronously. A finite element method (FEM) was used to numerically
calculate the distribution of pressure, distribution of temperature and the birefringence variety versus pressure and
temperature in two-mode highly birefringent photonic crystal fibers. Based on the single parameter sensor, the
muti-parameter sensor was analyzed. The results show that the muti-parameter sensor can measure pressure and
temperature synchronously.
